VOLCOTT A. IIULL, OF NEW YORK, N. Y.

DEVICE FOR CONTROLLING THE FLOW F LIQUIDS.

SPECIFICATION formingpart of Letters Patent No. 556,983, dated March 24,1896.

Application led May 27,1895. Serial No. 550,897. (No modell) To all whomt may concern:

Beit known that I, VOLCOTT A. HULL, of the city, county, and State ofNew York, have invented a certain new and useful Improvement in Devicesfor Controlling the Flow of Liquid, of which the following is aspecification.

My improvement relates particularly to devices for controlling the flowof water from the water-pipes of houses.

I will describe a device embodying my invention, and then set forth itsnovel features in the claims.

In the accompanying drawings, Figure lis a plan view of a deviceembodying my improvement. p Fig. 2 is a central section of the same,taken in a plane parallel to that of Fig. l. In this view other partsare also shown for the purpose of illustrating the invention. Fig. 3 isa sectional view at the plane of the dotted line 3 3, Fig. l.

Similar letters of reference designate corresponding parts in all thefigures.

I have illustrated my invention in the form of a coupling serving tounite a faucet of any suitable construction with a water-pipe. Thedevice is in effect a part of a faucet, and the invention may beregarded as embodied in a faucet, especially as it comprises a means forcontrolling the iiow of water through a waterway.

A designates an externally-screw-threaded nipple adapted to be screwedinto a correspondingpart comprised in a water-pipe. This nipple isconnected with one end of a chamber B, which at the other end has aninternally-screw-threaded portion b suitable for receiving anexternally-screw-threade d faucet C, as indicated in Fig. 2.

From the chamber B extends a conduit D, which at the outer end isprovided with a valve-chamber E, here shownA as made in the form of achamber for a compression-cock. Combined with the valve-seat of thischamber is a valve F, operated in the usual way by a stem f passingthrough a removable cap e.

It will be seen that the valve-chamber extends at right angles to theconduit D, and hence parallel with the chamber B. This is important,because it makes it possible to fasten the chamber B, by means of thenipple A, to a water-pipe, with the conduit D and valvechamber E closeto a wall, for, obviously, as the handle of the cock or valve extendsforwardly it will not'entail the necessity for providing any spacebetween the valve-chamber and the wall.

From the top of the valve-chamber E extends a nipple G, and with thismay be connected any suitable discharge pipe or nozzle. In the nipple Gis tted a swivel-pipe H, which is fastened into a swivel-piece h, thelatter being fitted into the nipple G. The lower end of thisswivel-piece is provided with a packing 72,', which impinges against aseat g. A tubular screw h2 secures the packing in place.

I designates a coupling-piece surrounding the swivel-pipe andswivel-piece and extending downwardly over the nipple G, it beingsecured to the latter by means of screw-threads. At the lower end it hasa iiange z', which impinges against a packing e" resting upon a shoulderformed exteriorly on vthe nipple. Within the coupling is a spring i2surrounding the swivel-piece h above a shoulder with which it isprovided and having bearings on the upper side of said shoulder and theinner side of the top portion of the coupling. Packing is may beinterposed between the spring and the top portion of the coupling toprevent leakage.

It will be seen that by my improvement I provide in a simple manner fortwo waterways in communication with one pipe under control of tworvalvesor cocks. One may be used for supplying water for washing purposes andthe other for controlling the passage of water through a filter fordrinking purposes.

It is advantageous to embody my invention in a coupling piece or devicesuch as is illustrated in the drawings, because then it renders the useof an ordinary faucet possible, as illustrated in Fig. 2.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A coupling-piece for connectingafaucet with a water-pipe, and havinga compressioncock communicating with the faucet, and having its stem andhandle extended forwardly, and a nipple communicating with thecoinpression-cock and extending upwardly, substantially as specified.

2. The combination with a water-outlet having an internally cylindricsocket, a pipe re- IOO ceiving water from said socket, and a swivelpiecemade independently of, but secured to, the last said pipe, and itted insaid socket, substantially as specified. 5 3. The combinationwithafaueet-body having Jtwo water-ways constructed to be separatelycontrolled, and an upwardly-extending socket with which one of thewater-ways communicates, of a pipe fitted to said socket, eX- tendingdirectly upward therefrom, oscillatory on its axis, having a passagethrough its` end, and a packing for maintaining a tight joint betweensaid socket and pipe, substantially as specified.

In testimony whereof I have signed my 15 name to this specification inthe presence of two subscribing witnesses.
